The only one I have read is Harry Potter, though I've looked at the 'Captain Underpants' books, and read part of Mice and Men.

I was also reading in the Guardian at the weekend that Mrs Gaskell banned her daughter from reading Jane Eyre until she was 20.
I tell you what, there are certainly books I would not have been happy with my kids reading when they were little. In fact my son left a copy of a Battle Royale manga lying about recently, and I told him to put in his room, because I didn't want my daughter to see it. So I'm not like 'Oh, little children can read Querelle of Brest and it'll be good for them'.
On the other hand, I used to read the Gollancz SF books my dad got from the library, when I was very young, and they were often not that suitable for an under-ten, and it never did me any harm *cough*.
Were your reading habits regulated in any way when you were a kid? By your parents, school etc?
